So sorry, just trying to help.
I'm the one that needs to apologize, and I do -- that last one came across way too harsh. Probably too much caffeine today.
But I looked through this thread and, unless I missed something, I don't see a single posted score over 300fps. Yours actually looks like the highest one.
I searched online outside of TPU and couldn't find a framerate score this high anywhere else, either. There was a Valley thread at OCN, but it died in 2020. This is just an ancient benchmark, and it's probably not all that suited to reflecting the performance of modern hardware.
But I think that you are on to something here, though, because I ran Valley a few more times and included other presets, and the results are consistent, almost as if there is a framerate cap or limit built into the engine or benchmark. And when it is running, the CPU and GPU core temperatures never exceed about 45C -- so both appear to be limited in the benchmark, but neither of them by the other. My 4090 temperatures typically max out at about 62C, and the CPU at 90C if it's being stressed really hard by AVX type stuff.
Probably better to just run these older benches for nostalgic or fun purposes.
